To all 'whom 'it may concern:

Be it known that I, ZEANrrH H. STAMETS, a citizen of the United States, residing at Auburn, in the county of Dekalb and State of Indiana, have invented certain new and useful Improvements in Filtering Apparatus. for Purifying Gasolene and other Liquid Fuels, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to filters for purifying gasolene and other liquid fuels, and has for its object to provide an improved filter in conjunction with a regulating device by means of which not only will the gasolene or other liquid fuel passing from a supply reservoir through the filter' to the apparatus which is to be supplied with the liquid fuel be thoroughly purified and foreign matter separated therefrom and deposited in a'receptacle, but also by means of which the flow of the liquid fuel will be regulated and the amount of liquidy fuel supplied will be automatically controlled and regulated.

Another object of the inventionis to provide a ilterrin conjunction with a sight gage by means ofwhich not only can the amount of liquid fuel in the main supply tank be readily ascertained and the decrease of the liquid fuel in the main supply tank indicated, but also by means of which an excess of liquid fuel from the main supply tank may be automatically regulated.

Another object of the invention is to provide in conjunction with a filter and a main supply tank containing liquid fuel, a secondary supply reservoir which contains purified liquid fuel.

Other and further objects and advantages of the invention will be apparent from the following detailed description and accompanying drawings.

In said drawings wherein a preferred and practical embodiment of the invention has been'shown-Figure 1 is `a central vertical sectional view of the improved filter, showing the same equipped with the' necessary pipes for connection with a source of fuel supply; a fuel regulator, and the device or other apparatus which is supplied with the purified liquid fuel. Fig. 2 is a similar view of the improved regulator. Fig. 3 is a de- 'tail plan view of the bottom plug cap of the filter. AFig.. 4 is a plan view of anstrainer disk carried by said bottom cap. Flg. 5 1s a` side elevation of a gasket used in connection with the lter. F ig. 6 is a top plan view of the filter. y A

Referring to said drawings by numerals, it will be seen that the improved filter is composed of a cylindrical vessel 1 having an open top and bottom, and preferably arranged vertically. 1 The .said top and bottom have their inner surfaces threaded, as indicated4 at 2 and 3 for the reception of sealing plug caps 4 and 5 theflanges of which are externally threaded.

The bottom cap 5 has its inner sides in clined as indicated at 6 so as to permit expansion and contraction of its contents, such for instance as water when the same freezes in cold weather. The central portion of said cap is provided with an opening 7 which is threaded for engagement with the threaded end of a drain cock 8 by means of which the contents of said cap 5 may be readily drawn off. Each of said caps 4 and 5 are provided witha nut formation 9 bymeans of which they may be readily manipulated to tighten or remove the same.

The upper end portion of the cylinder 1 is provided with oppositely disposed outstanding lateral nipples 10 and 1l which are eX- ternally threaded. Said nipples are prefer ably arranged indifferent vertical planes. A sealing gasket `12, preferably of cork or other suitable material, is surrounded by the cap 4 and has its flanged lower edge 13 in firm engagement with the outturned annular flat flange 14 of t-he lter 15, said annular fiange 14 resting on and clamped to an annular seat 16 formed in the cylinder l by meansl of said asket and the cap 4. Said gasket is provi ed with transverse openings 17 which register with the nipples 10 and 11,

the remaining openings 17 communicating with a space around said gasket and lpermitting the passage of gasolene 4or other liquid fuel. The said filter lois preferably formed of a single piece of closely woven fabric such as fine mesh brass gauze, which is shaped to form a central cone 18 which projects up into said cap 4, and a 'surrounding cone 19 the upper end of which terminates in4 the said .outturned fiat `flange 14. The filter extends well down into the cylinder el and its lower end terminates slightly above a partition plate or screen 20 horizontally varranged within the cylinder 1 and having. an: annular downturned annular ang'e 21 l which rests upon the end of the l provided with a pluralit threaded flange of thecap 5. Said plate is I of openings 22 which communicate with t e cap 5, said cap obviously forming a sediment chamber.

, their upper inner'surfaces, as indicated at 26.- The outlet'end of vsaid coil 25 rests on the plate 20 directly over one ofthe o enings 22 therein so that the discharge vom said end will bev directly into the cap 5.

v A horizontally arranged pipe`27 has a cap coupling 28 with the nipple 10 of the cylinder 1, the outer endof said ipe having a similar coupling 29 with an e bow or union 30 which in turn has asimilar cap connection 31 with a vertically disposed gage tube 33,- gasket packing 34 preferably o cork being interposed between the coupled end of said tube and said union. The gage tube 33 which is located at a 'suitable distance from a filter, is preferably of glass and its upper end is sealed by'means of a lflanged cap 35 having a pendent cage 36 which hangs within said tube. Said ca e is retained in spaced relation to the tube y means of an interposed cork gasket 37, and is provided with a flanged bottom 38 forming a seat for a ioat valve 39 preferably of cork coated with shellac or the like. The float valve 39 is hollow and its upper end is conical and its body is provided with parallel openings 40. A diaphragm 41 extends acrosstlie upper portion l tube 33.

of the cage, said diaphragm having inclinedP sides and a cent-ral opening 42 which is sealed by said float valve when the latter contacts therewith. A spout 43 projects exteriorly of the cage and overhangs the tub'e 33, said spout communicating with the cage through a reduced opening 4 4 formed therein. A set screw-45 projects .through the top of the cap 35 and is equipped with a Valve 46 for controlling the liow of air through said opening 44. A lock nut 47 may be employed for holding said set screw 45 in pre-determined positions.

The nipple 11 has a threaded engagement with a pipe 48 which communicates with the carbureter (not shown).

The liquid fuel supply tank, notvshown, is located in such a position relatively to the age tube 33 that the top of the liquid in the iquid supply tank will be on a level with the top ofthe column of liquid in the gage The operation of the device is as follows:v

openings or snaai filled with liquid, which also extends up into` the gage tube 33 to a heiglht equal to the height of the liquid in t e main sup ly reservoir, the gasolene or other liquid el in flowing throu h the coil 25 by means of the circulation ofg the liquid passin olf from the filter through the pipe 48`to t e device or' apparatus beingsup ied, passes with a whir mg movement to t e lower end of the coil 25 and such whirling movement causes, by means of centrifugal force, the heavier particles of foreign matter yin the liquid to e carried against the outer side if the inside of the coil opposite to that in which are located the erforations 26, while the lighter particles ofp the liquid-that is to say, the gasolene or other liquid fuel-passes out of the apertures 26 and toward the center of the filter and through the screen. The heavier particles and the foreign matter held within the coil pass down through the same and out of its lower end, the whirling motion of theflow of the liquid causin the foreign matter so passing out of the coil 25 to be carried to and through the several assageways 22 in the screen 20 and to be eposited in the sediment chamber or cap 5. The liquid in the gage tube 33 is' regulated by air admitted through the spout 43, the amount of air admitted being governed by the adjustment of the set screw 45. Said means for regulating the admission of air is preferably employed but that may be dispensed with and the top of the gage tube be lentirely open.

The device herein set forth may be used with any device or'apparatusto be supplied with purified liquid fuel and is especially adapted for use with automobiles or other gasolene engines. When used w'th an automobile, t-he delivery pipe 48 communicates with the carbureter and by means of this invention the forei n matter is entirel separated from the llquid fuel, the car ureter supplied' with the purified gasolene and prevented from choking. When used with an automobile, the gage tube 33 supplied with the float valve 39 serves to automatically control and regulate the supply of li uid fuel to the carbureter, when the automo ile is at an incline, since when in such a p'osition the liquidfuel from the main supply tank backs into the ga e tube 33, the li uid in the tube will cause t e float valverto c ose the opening 42 and thereby prevent a discharge of oil through and out of the upper end of the ga tube 33. Furthermore 'the flow of liqui through the filter to acarbureter is automatically regulated by the sight gage alone, serving as an auxiliary reservoir, since owing to the fact that the flow of the liquid from the carbureter to the engine is normally irregular on account of the pulsations of the engine, an equal pressure of the liquid between the carbureter and the main supply tank is maintained yby the volume of liquid in the sightl ga re.

lf desired, the supply of liquid fuel from the main supply tank may be cut off by closing the valve 2l, and in such case the gage tube 33 will serve as a reservoir for the purified liquid fuel.

By means of this invention the filter is self cleaning since the action of the Whirling liquid through the perforated coil causes the screen to be kept free from foreign substances.
